AUGUST SCHUBERT, ONEIDA, NEW YORK.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 388,587, dated August 28, 1888.

Application filed March 26, 1888.

To all whom it may concern:

Be it known that 1, AUGUST SOHUBERT, of Oneida, in the county of Madison, in the State of New York, have invented new and useful Improvements in Vehicle-Springs, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of springvehicles in which the bodyis supported on side springs carried at opposite ends on the ends of cross springs mounted on the hind axle and head-block.

The invention consists in a novel construction of the coupling which connects the side spring with the cross-spring, as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a side view of a vehicle-spring gear embodying my Fig. 2 is a top plan View of the same. Fig. 3 is an enlarged side view of the spring-coupling. Fig. 4 is a vertical transverse section of said coupling, taken in a plane at right angles to the side spring. Fig. 5 is a vertical longitudinal section of thesame in a plane parallel with the sidespring. Fig. 6 is a side View of a modification of the coupling; and Fig. 7 is a vertical transverse section of said modification, taken in a plane at right angles to the side spring.

Similar letters of reference indicate corresponding parts.

S S represent the side springs, and S S the cross-springs. The cross-spring S, I form with a shackle-eye, c, at each end. This eye is of cylindrical form, and upon the same I place a saddle, a, of semi-cylindrical form,fit-

ted closely to the top portion of the eye 6, so as to snugly ride thereon and relieve the coupling-bolt b from strain. Said saddle is formed with pendent perforated cars a. a. at opposite ends of the shackle-eye c, and the aforesaid coupling-bolt passes through said ears and intervening eye, and is provided with the usual head at one end and with a nut at the opposite end. The saddle a is also formed with a transversely-perforated rocker-seat, c, of the form Serial No. 268.544. (No model.)

der side of a plate, P, secured to the end of the side spring, S. From said plate project downward perforated ears ff, which embrace between them the aforesaid rocker-bearing, and are hinged thereon by a bolt, h, passing through said ears and intervening rockerbearing. Said bolt is also relieved from strain by the riding of the concave bearing upon the rocker-bearing.

It will be observed that the described coupling carries the side spring upon the cross spring and allows both springs to freely vibrate independent of the coupling-bolts, and is therefore perfectly safe in its operation. In order to allow the side spring when subjected to a load to elongate or expand without straining the cross-springs laterally, I make the saddle a of sufficient length to allow a rubber pad or cushion, i, to be introduced between the rear end of the eye e of the front crossspring and adjacent ear a of the saddle a, said cushion being retained thereon by the coupling-bolt b passing through it. A similar cushion may be also applied between the front end of the eye a of the rear cross spring and adjacent ear a of the saddle a.

The plate P is firmly secured to the end of the side spring by a recessed seat, t, in the top of said plate, in which seat the end portion of the side spring is inserted, and rivets,passing' vertically through said end portion of the spring and through the plate P, securely unite said parts.

I do not limit myself to the arrangement of the concaved bearing d o n plate P, riding on the rocker-seat a, formed on the saddle a, as it is obvious that said bearing and seat maybe reversed in their position z'. e., the concaved bearing (1 may be formed on the saddle a and the seat a formed on the plate 1?, as illustrated in Figs. 6 and 7 of the drawings.

Having described my invention,what I claim as new, and desire to secure by Letters'Patent, 1s

1. In combination with the side spring and cross-spring, the shackle-eye 6, formed on the end of the cross-spring, the saddle a, riding on said eye and formed with the perforated segmental rocker-seat c on top and with pendent perforated ears aa at the ends of the eye, the coupling-bolt Z), extending through said ears and intervening eye, the plate 1?, secured to the end of the sidespring and formed with the concave bearing 01, riding on the seat a, and provided with the perforated earsff, and the coupling-bolt h, passing through said ears and intervening rocker-seat, substantially as described and shown.

2. In combination with the side spring and cross-spring, the shackle-eye 6, formed on the end of the cross-spring, the saddle (1-, provided with perforated ears a a, the cushion 2', interposed between the end of the shackle-eye e and adjacent ear a, the coupling-bolt 1), extending through said ears and intervening shackleeye and cushion, and the plate 1?, attached to the end of the side spring and coupled to the saddle a, substantially as set forth and shown.

3. In combination with theside spring,crossspring, and the saddle a, connected to the end ofsaid crosssp ring and formed With the rockerseat 0, the plate 1?, formed with the recessed seat It for the end ofthe side spring,and formed, also, with the concave bearing 01, riding on the seat 0, and with perforated earsff, and the
